0.045~8.0mm Slot Size Polyurethane Screen Mesh with High Wear Resistance for Coal Washing Plant

Designed to achieve micron-level separation efficiency, our vibration-enhanced polyurethane screen mesh employs 0.045mm (325 mesh) precision apertures tailored for silica-rich materials like quartz sand and industrial glass precursors.

By integrating specialized polymer compounds with high-speed oscillation systems, this solution maintains over 97% operational efficiency across abrasive conditions while preventing aperture obstruction. The tapered slot geometry actively channels particle flow, enabling uninterrupted wet/dry processing cycles.

Featuring a 35-40% free surface area and 85-95 Shore A resilience, it delivers 5-10x greater durability than metallic alternatives alongside 25%+ capacity improvements in mineral processing workflows.

• Pore Dimensions: 0.045mm (325 mesh) to 8.0mm adjustability
• Composite Material: Reinforced polyurethane with wear-resistant additives
• Operational Thermal Range: -4°F to 176°F (-20°C - 80°C)
• System Integration: Compatible with high-G vibrating decks

1. Material Preparation: High-grade polyurethane raw materials, including pre-polymers and curing agents, are meticulously selected based on abrasion resistance and elasticity requirements. Additives such as UV stabilizers and anti-aging agents are blended to enhance longevity in harsh environments.
2. Mold Design & Fabrication: Precision CNC-machined molds are crafted from stainless steel or aluminum, incorporating the exact aperture geometry (e.g., 0.045mm wedge-shaped slots). Mold surfaces are polished to a mirror finish to ensure smooth demolding and dimensional accuracy.
3. Casting & Curing: The liquid polyurethane mixture is vacuum-degassed to eliminate air bubbles. It is then poured into preheated molds and subjected to controlled-temperature curing (80-120°C) in hydraulic presses. This step ensures uniform density and structural integrity. Post-curing thermal treatment further enhances tensile strength and chemical resistance.
4. Demolding & Trimming: Cured screens are carefully demolded, and excess flash is removed using laser trimming or precision cutting tools. Edge sealing is applied to prevent delamination during high-frequency vibrations.
5. Quality Control: Aperture verification using laser scanners measures aperture sizes (0.045mm ±0.005mm) and open area ratios (35%-40%). Durability testing includes simulated high-frequency vibration cycles (up to 3,600 RPM) to assess fatigue resistance. Material certification validates Shore hardness (85-95A), tear strength, and chemical compatibility per ISO 9001 standards.
6. Surface Treatment (Optional): Anti-static coatings or custom-colored finishes are applied for specific industrial requirements, such as explosive environments or visual inspection needs.
7. Packaging & Logistics: Screens are packed in moisture-proof, shock-absorbent materials and labeled for traceability. Custom sizes and OEM branding are accommodated seamlessly.
